Purple Biotech (NASDAQ/TASE: PPBT) reported positive final results from its randomized Phase 2 study of CM24 in second-line pancreatic cancer. The study evaluated CM24, combined with nivolumab and Nal-IRI/5FU/LV chemotherapy, showing significant improvements across efficacy endpoints. In a biomarker-enriched patient population, the treatment demonstrated a 79% reduction in death risk (HR 0.21, P = 0.04) with 5.1 months median OS improvement, and over 90% reduction in progression risk (HR < 0.1, P = 0.003) with 2.9 months median PFS improvement. The company plans to proceed with a Phase 2b study in multiple selected indications, targeting patients based on biomarkers.
Purple Biotech (NASDAQ/TASE: PPBT) reported Q3 2024 financial results and clinical updates. The company expects topline data from Phase 2 CM24 pancreatic cancer trial by end of 2024. New biomarker data showed patients with specific serum CEACAM1 levels demonstrated 79% reduction in death risk. Q3 financial highlights include reduced R&D expenses to $1.3M (71.7% decrease), operating loss of $2.1M (63.2% decrease), and net loss of $0.7M. Cash position stands at $6.3M with runway extending into Q4 2025. The company plans to commence Phase 2 study of NT219 in head and neck cancer in H1 2025.
Purple Biotech has identified serum CEACAM1 as a potential new blood biomarker for its lead oncology candidate CM24. Pancreatic cancer patients with serum CEACAM1 levels between 6K-15K pg/mL showed significantly improved outcomes when treated with CM24 and nivolumab combined with chemotherapy. The treatment demonstrated a 79% reduction in death risk, improving median overall survival from 3.6 to 8.7 months, and progression-free survival to 4.6 months. CM24, a CEACAM1 inhibitor, is currently in Phase 2 trials with topline results expected in Q4 2024.
Purple Biotech presented new data for its CAPTN-3 platform at the EORTC-NCI-AACR Symposium. The platform demonstrates sustained tumor regression in triple negative breast cancer models and dose-dependent activity in non-small cell lung cancer. The lead tribody IM1240 showed 5T4-dependent cytokine release with improved safety profile through conditional activation. The platform enables development of tri-specific antibodies targeting both T cells and NK cells to fight cancer, with potential first human clinical studies by 2026. The technology showed synergistic effects in tumor suppression and demonstrated plug-and-play capabilities for targeting different cancer types.
Purple Biotech (NASDAQ/TASE: PPBT) has been selected to present data on its CAPTN-3 platform at the 36th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Spain, from October 23-25, 2024. The poster, titled "CAPTN-3: A novel platform of conditionally activated T cell and NK cell engagers," will be presented by Dr. Hadas Reuveni, VP R&D of Purple Biotech.
CAPTN-3 is a first-in-class platform of conditionally activated tri-specific antibodies that engage both T cells and NK cells with tumors, creating an enhanced immune response against cancer. The company's lead candidate, IM1240, targets 5T4, a tumor-associated antigen overexpressed in various solid tumors and linked to poor clinical outcomes. 5T4's specific expression pattern in cancer cells makes it an ideal target for therapeutic approaches in lung, gastric, head and neck, and other cancers.
Purple Biotech (NASDAQ/TASE: PPBT) reported positive interim data from its Phase 2 study of CM24, its lead oncology therapeutic candidate, for pancreatic ductal adenocarcinoma (PDAC) treatment. Key findings include:
1. High CEACAM1 and low PDL1 expression in tumors associated with improved overall survival (OS).
2. Improved OS for patients with serum neutrophil extracellular trap (NET) marker myeloperoxidase (MPO).
3. NETs proposed as a novel mechanism of action and potential biomarker for CM24-based therapy.
4. Data supports potential for biomarker-led studies and exploration of CM24's efficacy in other cancers.
The study evaluates CM24 combined with nivolumab and chemotherapy as a second-line PDAC treatment. Topline data expected in Q4 2024.
